How Does a Hydraulic Motor Function in a System?

AI Thread Summary
A hydraulic motor functions by using pressurized fluid to push against vanes attached to a shaft, causing it to rotate. The fluid is then drained back to the pump, which is essentially a reversed hydraulic motor that generates pressure by turning a shaft with vanes. Solenoid valves control the flow of this pressurized fluid into the motor, enabling precise movement. The discussion highlights the relationship between hydraulic motors, pumps, and valves, emphasizing their roles in converting hydraulic energy into mechanical energy. Understanding these components is crucial for applications like cranes and spreaders in port operations.

Hey Respected seniors,
I want to know that how the hydraulic motor works?
Im working as a trainee engineer in a company..
I watch daily a machine that have hydraulic motor, pump, solenoid valve...
All these things are for the movement of a shaft which is connected to a jack( I see, there are two cables/nozzles for pump pressures attached with that jack..). ..

PLZ simply tell me how the hydraulic motor, pump, solenoid valve work together?

thanx & best regards

Hydraulic motors are basically water wheels. A fluid under pressure pushes against vanes attached to a shaft and makes the shaft turn. After doing a little pushing the fluid is drained from the motor and returned to the pump that pressurized it. The pump itself is just a reversed version of the motor -- something turns a shaft that has vanes which pushes fluid out of a port under pressure.

There should be some good diagrams of these things on wiki or google someplace if you poke around a bit.

Beating the analogy a little further, this is pretty much how an electric motor or generator works as well...see the Hydraulic Analogy.

thanx alot...
 
Actually the machine that I discussed is a SPREADER which is used with CRANES(ship to shore,sts, and rubber tyre gentry,RTG)..
So If anybody is working at PORT then I request him, please tell me in detail,thanx

The specific application is pretty much irrelevant, except perhaps as regards scale. The pump (vane or lobe type), under the influence of a drive motor, supplies pressurized oil to the motor (which is just a pump fed from the other end). The valve, whether electrical or mechanical, controls the flow of oil into the motor. I don't quite understand the particular matching of a motor with a cylinder (which you called a jack) in this instance.
 
how a hydraulic motor works

The hydraulic motor is the component of a Hydraulic System that convert hydraulic Energy from the hydraulic system into mechanical rotational Energy by rotating the shaft.

This is a good explanation of the subject.

Take a look at this video:

I hope this is what you are looking for.

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
